PYSEC-2021-94.yaml

id: PYSEC-2021-94
details: An issue was discovered in Pillow before 8.2.0. For BLP data, BlpImagePlugin
  did not properly check that reads (after jumping to file offsets) returned data.
  This could lead to a DoS where the decoder could be run a large number of times
  on empty data.
